UK Prime Minister Boris Johnson has called on nations to “collectively cease their dependence” on Russian oil and gas and threatened “massive” economic sanctions after Russia’s President Vladimir Putin ordered an invasion of neighbouring Ukraine on Thursday.

Johnson said reliance on Russian oil and gas supplies has "for too long given Putin his grip on western politics".

Johsnon said: "In concert with our allies, we will agree a massive package of economic sanctions designed in time to hobble the Russian economy."
